TO ALL WHOM IT 'MAY CONCERN:

Be it known that I, GEORGE'T. PALMER, Of BrookIyn in the county of Kings, and State of New York, have invented anew and useful Article to'Placein the Bottom of a. Boiler-Pot, for the purpose of preventing food or'other articles from being'burned when'ibeing boiled; ailrl I do hereby declare that the following is a. full and exact description thereof, reference being bad to. the accompanying drawings and the letters of reference marked thereon.

. Similar letters denote like parts.

Figure 1 is a, topview of my extra bottom-for a boiler-pot. V

Figureffl is-a centralvertical seetion ot the same, showing itsposition in a pot, which is also shown'in section. I V i A In figs. 1 and 2, ads the top or flat part of the extra bottom, which is perforated with holes, d d. ,bisa depressed rim. 0 is a handle. A'is a cooking-pot.

The extra bottom is'shown in 2, in position as when being used. I I

The rim 6, by being turned down, stiifens the article, and serves the purpose of raising the flat part, u to the desired height from the bottom of-tlre pot.

The depressed rim may be made in various ways, such as havingholes through it, as shown infigs. 1. and 2,

or the rim may be made plain, and have a corrugated edge, or small knobs to raise the edge'from close contact with the bottom ofthe pot.

The circulation of the liquid ina pot provided with at! extra bottom, asshown, will be mnch more perfect than would be'the case without it, as all solids resting on the bottom of the pot are impediments to the free circulation of the fiuidscontained therein, and are liable to beingbnrned.

The loop or handle a may be fixed in its position, or it may be hinged, so that it may be turned flatupon the part a, for the purpose of being packedmore closely.

Theextra. bottomiis made of tin, zinc, or other suitable material, but ti'n has special qualities which make it best adapted for the purpose.

Having thus described my invention, I-claim, as a new article of manufacture- A perforated plate, a Z), with adepressed rim-and handle, 0, made substantially in the manner shown, and

for the punpose set i'orth.

' GEORGE T, PALMER.
